Definitions
- the invention relates to an apparatus for producing a three-dimensional part, particularly a laser sintering machine and, more particularly, a synthetic material laser sintering machine.
- Known laser sintering machines comprise a machine housing in which a sinter building space or process space is arranged. In the upper region of this building space, the exit optics of a sintering laser in the form of a scanner are located.
- the scanner constitutes the optical system for deflecting the laser beam providing the energy required for sintering the sinter material (thermoplast powder).
- a work piece platform being height adjustable and above which material feeding means including a coating device are provided, designed for feeding powdery sinter material from a reservoir in the process area of the work piece platform.
- the part is built in a layer-by-layer fashion in the inner region of the height-adjustable work piece platform.
- a rim serving as a delimitation of the work piece platform is formed, i.e. sintered, substantially simultaneously at the periphery of the platform.
- rim fractures or rim damages cause some powder to drop into the lower region of the laser sintering machine, soiling this portion and thus causing additional servicing and down-time of the laser sintering machine.
- the sintered part as well as the delimitation have to remain in the laser sintering machine for a certain period after the actual production process, in order to obtain a degree of curing and cooling such that deformations of the edge and of the part will no longer occur during withdrawal.
- a building time of 20 hours would also require a cooling time of roughly 20 hours for the built rim and the part, such that prior art laser sintering machines have relatively long down-times.
- the invention provides an apparatus for producing a three-dimensional part by successive layer-by-layer solidification of a solidifiable material at locations corresponding to the cross section of the part, and having a building space ( 3 ) provided in a machine housing, characterized in that an interchangeable container ( 12 ; 112 ) forming a delimiting frame for the material ( 9 ) can be inserted within said building space ( 3 ), in which a work piece platform ( 8 ; 108 ) is integrated and a supporting device is arranged, on which the work piece platform ( 8 ; 108 ) is supported and/or mounted during operation of the apparatus.
- the work piece platform is adjustable in height within said delimiting frame and integrated in the interchangeable container as a container bottom;

- the interchangeable container ( 12 ) in plan view has a substantially square or rectangular cross section and comprises four side walls ( 14 ) substantially perpendicular to each other, in which said work piece platform ( 8 ) is guided in a height-adjustable manner;
- the supporting device ( 40 ) is incorporated in the lower portion of said interchangeable container ( 12 ) and is therefore a fixed component of said interchangeable container ( 12 );
- the interchangeable container ( 12 ) can be inserted into guides ( 70 ) in the portion of the side walls ( 14 ) of said building space ( 3 );
- the interchangeable container ( 12 ) is provided at its upper end with supporting angles ( 71 ) laterally extending away and resting on the guides ( 70 ) of said machine housing ( 2 );
- roller shutter ( 34 ) is a steel roller shutter
- the work piece platform ( 8 ) is formed by two spaced bottoms arranged in parallel to each other, the upper bottom forming the work piece holder and the lower bottom resting on said supporting device ( 20 );
- magnet elements ( 4 ) cooperating with said roller shutter ( 34 ) are arranged adjacent to said engagement recesses ( 33 );
- roller shutter ( 34 ) is guided by a deflection pulley ( 60 ) the rear edge of which is aligned with the inner surface of the rear side wall ( 14 ′);
- a powder compression element is active between the inner sides ( 15 ) of the side walls ( 14 ) of said interchangeable container ( 12 ) and the outer edges of said work piece platform ( 8 );
- the powder sealing element is formed by a silicone plate, the outer dimensions of which are adapted to the inner dimensions of said side walls ( 14 ) of said interchangeable container ( 12 );
- the work piece platform ( 8 ) is connected to said supporting device ( 20 ) during the process;
- the interchangeable container ( 12 ; 112 ) comprises a recess ( 33 ; 133 ) through which the supporting !device ( 300 ; 30 ) is engaged and in which the supporting device can be displaced;
- the recess ( 133 ) is formed in a slot-shaped manner in the direction of displacement of the supporting device and is sealed by means of a tape ( 200 ) mounted to the wall of said interchangeable container above said recess and being pressed against the container wall surrounding said recess ( 133 ) by said work piece platform ( 108 );
- the tape ( 200 ), at its other end, is clamped in the region of the lower edge of said interchangeable container and has a constant length between the points at which it is clamped;
- the tape is tensioned at the lower side of said work piece platform via at least two slideways ( 202 , 203 ) arranged in the vicinity of the edges of said work piece platform;
- the tape is formed as a steel tape
- the supporting device ( 40 ) engages said interchangeable container ( 12 ; 112 ) from underneath and is connected with a telescoping linear guide for raising and lowering said work piece platform;
- a working plate ( 118 ) is provided in said building space ( 3 ), said working plate comprising a device ( 121 ) for clamping said interchangeable container ( 112 ) at the bottom side of said working plate ( 118 );
- a coupling device ( 300 ) for coupling and decoupling said supporting device to said work piece platform ( 108 ) is provided;
- a controllable heating device is provided in said interchangeable container ( 12 ), particularly in its side walls ( 14 ) and/or said work piece platform ( 8 );
- the supporting device is designed such that a space required for lowering said interchangeable container is provided without displacing said supporting device in the vertical direction;
- an interchangeable container forming a delimiting frame is inserted into said sinter building space, said work piece platform being integrated in said interchangeable container as a bottom and a supporting device being arranged in said interchangeable container, on which said work piece platform is resting during operation of the laser sintering machine.
- the novel interchangeable container insertable into said sinter building space is substantially composed of two core components, one being a shaft-like outer portion forming the delimiting frame and the other one being the regular work piece platform which is integrated in this shaft-like portion in a height-adjustable fashion.
- the container bottom within the delimiting frame is lowered gradually, and the area above the work piece platform is repeatedly filled with powdery sinter material, which is carried out in-a conventional manner by the coating device.
- the work piece platform can be lowered via the supporting device into a lower portion and by means of locking elements such as sliding plugs which can be inserted into bores aligned with each other between the walls of the interchangeable container and the work piece platform, the container bottom is firmly connected with the container side walls. This connection may then be released from the supporting device and lifted off and withdrawn from the building space. This can be done trouble-free in the hot state.
- the cooling of the container, the part contained in it and the sinter material takes place outside the sintering machine.
- a new interchangeable container can be inserted, its bottom connected with the supporting device and thereafter unlocked from the side walls of the interchangeable container. After a change-over time of about 15-20 minutes, the sintering machine is again ready for the next laser sintering job.
- the invention has several advantageous effects on the operation of such a sintering machine.
- building errors in the periphery do not result in the actual part ending up as a reject.
- the cooling times of the part and the material surrounding it are transfered out of the sintering machine.
- the sintering machine is very rapidly made available again for a new job. Also, both sinter material and energy are saved.
- the interchangeable container as viewed from the top, has a substantially square or rectangular cross section and comprises four side walls substantially perpendicular to each other. Within these side walls, the work piece platform is guided in a height-adjustable manner.
- the supporting device engage from underneath into the shaft of the container side walls or as well integrate it as an integral part into the interchangeable container.
- the rear container wall of the interchangeable container preferably comprises engagement recesses extending in the displacement direction, i.e from the bottom to the top, through which a supporting device adjustable in height in the rear side wall portion of the building space can engage with support arms substantially extending in the horizontal direction.
- the solution where the supporting device for supporting the work piece platform engages the interior of the interchangeable container by means of support arms through one of the side walls of the interchangeable container, is advantageous compared to a solution where one support arm engages the interchangeable container for supporting the work piece platform from underneath, since space which would have to be reserved for the supporting device below the interchangeable container can be saved and used as building space for building larger parts.
- the solution where the support arms or one support arm laterally engage the wall of the interchangeable container however, always requires the sealing of the engagement recess for a support arm above the work piece platform in order to prevent powder from falling out.
- a device for sealing in the form of a roller shutter secured to the upper edge of the interchangeable container and coming to rest on the inner side of the container wall and covering the engagement recesses when the work piece platform is lowered.
- holding magnet elements cooperating with the steel roller shutter are arranged. Due to the holding magnet elements, the steel roller shutter closely fits the inside of the rear container wall such that no or only very little powder can fall into the lower machine portion.
- the interchangeable container comprises a slot-shaped center recess on the rear wall extending in the longitudinal direction, with a support arm for supporting the work piece platform engaging into said recess.
- a tape preferably made from steel, instead of the steel roller shutter is provided which is clamped at the upper edge of the rear wall and at the bottom of the interchangeable container, respectively, in a region substantially diagonally opposed to the upper edge.
- the steel tape is guided along the engagement recess and at the bottom side of the work piece platform and is tensioned via gliding cylinders.
- the steel tape has a fixed length between its clamping points and due to the guiding along the bottom side of the work piece platform, it is always pressed with the correct length against the engagement recess above the work piece platform.
- the embodiment using the tape has the advantage that the tape is less expensive and can easily be replaced when worn or damaged.
- the tape is nearly free of forces.
- the previously described roller shutter has a strong spring for winding. Nevertheless, with the tape, there is no need to lock the work piece platform in the lower position. The friction of the seal is sufficient to stabilize the work piece platform.
- the interchangeable container In the upper portion of the container, holding or hooking elements are provided to limit the replacement process to only a few manual steps. It is of particular advantage if the interchangeable container can be inserted in a drawer-like fashion into the process space, with guides being provided in the region of the side walls of the process space and the interchangeable container being equipped at its upper end with supporting angles and the like laterally extending away and resting on the guides of the process space.
- the laterally protruding supporting angles provided at the interchangeable container are not resting on guides in the region of the lateral walls of the process space, but are fastened from underneath, lifted and pressed against the working plate by a clamping device which is provided at the working plate provided in the process space and extending horizontally and having a recess corresponding to the contour of the interchangeable container.
- the support arm comprises a coupling device permitting very easy coupling to and decoupling from the work piece platform.
- a hoist is further provided, which can be driven into or next to the building space and on which the interchangeable container can be transported.
- the entire building space is heated.
- This type of building space heating is relatively slow and energy intensive.
- the heating can be suitably adapted to the thermal requirements of the laser sintering process.

- the pivot mechanism consists of a knee lever system of two knee levers 309 each having a first leg 309 a hinged with its one free end at the adjacent support plate 306 and having a second leg 309 b pivotally connected to each one of the first legs 309 a at its free ends and commonly provided for both knee levers and pivotally mounted on a cross strut 310 connecting the struts 305 .
- a pivot lever 311 is arranged at the second leg 309 b by which pivot lever 311 , when actuated, the knee lever system may be actuated. To that end, the pivot lever acts on the second leg 309 b such that it can be rotated relative to the cross strut 310 .
- the pivot lever 311 When the pivot lever 311 is pivoted the knee levers can be brought from their stretched state to their folded state and vice versa, permitting the support plates to be pivoted from their upright state into the folded together state and vice versa.
- the clamping device 121 is initially located in the empty building space 3 in the position where the gripping rod 128 is on the upper side, i.e. facing the working plate 118 .
- the connecting point of the legs 123 a , 123 b of the knee levers is then located in a first lower position and the ends of the legs 123 a , 123 b are facing towards the working plate 118 .
- an empty interchangeable container 112 will be introduced into the building space 3 such that the laterally protruding support angle 171 will be shifted into a position between the first leg 123 a of the knee levers 123 shown in FIGS. 6 and 7 and the frame portion 122 .
- the pin 172 comes to rest with its free end 173 on the second section 129 b of the respective connecting part.
- the gripping rod 128 is pushed down such that the interchangeable container will hit the support 122 b . Due to the centering motion of the interchangeable container, the pin 172 will glide on the sloping surface of the second section 129 b until it will come to rest on the third surface 129 c (FIG. 8 c ).
- the first leg 123 a is horizontally aligned while the second leg 123 b is pointing downwards with the end position of the gripping rod 128 being given by the support 128 a .
- FIG. 8 c the first leg 123 a is horizontally aligned while the second leg 123 b is pointing downwards with the end position of the gripping rod 128 being given by the support 128 a .
- the dimensions of the clamping device are such that the center of gravity of the container will be roughly below the location of the support of the pin 172 .
- the interchangeable container is clamped against the supports in the frame portions 122 and thus against the working plate 118 which forms an abutment, the clamping being substantially carried out by spot interaction of the clamping force of the first legs 123 a and the respective pin.
- the work piece platform 108 initially located in its lowermost position, will then be coupled to the support arm 300 previously introduced from underneath, whereby the pivot lever 311 is brought in the position shown in FIGS. 9 and 10, causing the knee levers 309 to be brought into their stretched position and thus the support plates 306 being pivoted into their upright position.
- the pins 308 are pressed into the sockets 206 of the holder 205 , causing the support arm to be coupled. The positioning is carried out vertically by means of the sockets resting on the part 306 .
- the building of the part in the interchangeable container can take place.
- the work piece platform supported by the support arm, is displaced towards its uppermost position by actuating the height displacement means and a layer of a powdery material will be deposited and sintered at the locations corresponding to the part.
- the work piece platform is lowered by a distance corresponding to the layer thickness and the new powder will be deposited.
- the engagement recess is simultaneously sealed by the steel tape 200 such that no powder will fall out through the engagement recess 133 . Due to the guiding of the steel tape at the bottom side of the work piece platform 108 , it is guaranteed that the part of the engagement recess located above the work piece platform will always be covered.
- the work piece platform is transferred into the withdrawal position (lowermost position of the work piece platform).
- the work piece platform is decoupled from the drive by pivoting the pivot lever to the right, causing the support plates 306 to be pivoted into the position shown in FIG. 12 .
- This process generates sufficient space in the vertical direction for lowering the interchangeable container.
- This lowering is carried out using the elevating and clamping device described above by carrying out the steps according to FIGS. 8 a to 8 c in the reverse order.
- the interchangeable container together with the part formed in it will be withdrawn.
- the interchangeable container is then transferred to a location for further processing or cooling.
- the interchangeable container is taken out by means of a hoist (not shown) which can be driven into or close to the building space.
- a hoist not shown
- the interchangeable container including the part formed therein which can be very heavy, does not have to be carried by hand.
- the space required for lowering the interchangeable container is not created by displacing the z-axis.
- the maximum possible displacement distance can entirely be used for the building of parts.
- the invention is not limited to a laser sintering machine. It can be applied to all rapid prototyping devices where a part is built in a layer-by-layer fashion on a building or work piece platform from a material that can be solidified.
